摘要
为了研究车辆主动悬架时频响应特性,以主动悬架1/4车辆模型为研究对象,依据车辆系统动力学理论建立了1/4车辆主动悬架动力学模型,利用Simulink对悬架和车身加速度进行仿真,对不同车速下的路面高程曲线的频谱和车辆固有频率进行分析。研究结果表明,仿真车辆在B级公路以60km/h车速行驶时,路面激励引发车辆共振。
In order to research on the time-frequency response of the vehicle active suspention, based on quarter vehicle of active suspention,using the theory of vehicle system dynamics to establish quarter vehicle model of active suspention, the active suspention and acceleration of body were simulated by Smulink software. Analyze the frequency spectrum of road excitation under different speeds and natural frequencies. Simulated results indicate that the road excitation caused vehicle resonance when the speed of vehicle is more than 60km/h on the B-class road.
